Alternative modeling methods for plasma-based Rf ion sources.
Rf-driven ion sources for accelerators and many industrial applications benefit from detailed numerical modeling and simulation of plasma characteristics. For instance, modeling of the Spallation Neutron Source (SNS) internal antenna H(-) source has indicated that a large plasma velocity is induced near bends in the antenna where structural failures are often observed. This could lead to improv...
متن کاملSputter Probes and Vapor Sources for ECR Ion Sources
Sputter probes are a promising method for injecting controlled quantities of metallic elements inside ECRIS, provided that the sputter rate can be controlled, so that high charge states and low sample consumption rate will be attained. Moreover pressure at the probe and inside the source should be different. With a sputter probe distance of 25 mm from ECRIS plasma, a 200 nA current of Sn was ea...
متن کاملDesign of a Microwave Frequency Sweep Interferometer for Plasma Density Measurements in Ecr Ion Sources∗
Electron Cyclotron Resonance Ion Sources (ECRIS) are among the candidates to support the growing request of intense beams of multicharged ions. Their further development is related to the availability of new diagnostic tools, nowadays consisting of few types only of devices designed on purpose for such compact machines. Microwave Interferometry is a non-invasive method for plasma diagnostics an...
متن کاملRefractory Ovens for Ecr Ion Sources and Their Scaling
The radiofrequency (rf) oven can be used as a metal vapour injector for Electron Cyclotron Resonance ion sources; the application to high temperature boiling metals (like Cr, Ti and V) was recently demonstrated. Duration and reusability of oven parts were good, since only crucible needs to be maintained at a high temperature Ts. For vanadium case, achieved Ts was over 2300 K with about 280 W of...
متن کاملSuperconducting Ecr Ion Sources: High Intensity Beams Extraction and Transport
In the last decade a relevant step forward in the design of Electron Cyclotron Resonance Ion Sources (ECRIS) have been obtained and some high performance sources have been built, at the operating frequency of 14,18 and 28 GHz. In particular, the total extracted current exceeds 5 mA in cw mode for some of them, at voltage between 10 and 40 kV. A potential drawback of such intense beams consists ...
